y IMPROVEMENT IN HEA'rlNe-s'rovEs.

1 Tdall whom it 4may concern: ,f Be it known that We, WrLLIAM GOTTINGHAM and.V JOHN W; STAFFOnD, of Troy, iu the county of Miami l and State of Ohio, have `invented a new and improved Heating-Stove; and we dohereby declare the following tobe a` full-,` clear, and exact description ofthe same, reference beinghad to the accompanying drawingfu'iaking` apart oi' this specification, in which- Figure lfis a sectional elevation, and Y Figure tfis a;` plano'f `the central and side drums,

, with the top of the jacket removed.

N This'finventi'onrelates to a combination of drums placed within an inclosing jacket,4 and provided with 1, peculiar facilitiesfor supplying the lnaindrum with.

fuel and forcleaning `the, smaller side drums, the

whole-forming afurnace that can be'made to radiate Vas much or as littleheat as required, and is very sim ple'and cheap..

vReferring tothe drawing;-

` c isthe main drum; andl b c d arefsmaller sidedrums, 'placed parallel to thev main drurd and to 'eafclrother,V the rst ofthe series,

"b,.being connectedfwith the main-drum by a short pipe, c, placed near the top of both, through which the products of' combustion' escapeifrom thelarger to the sipallerdrnm." l f 1 `jlis a pipe that connects the drums b and.cand is `placed lower than the, pipe c.:

11. is a pipe ,that connects the druumsc andi?, and is placed either higher or lower than the pipe f t is the" pipe through which `the products ot com-` bustion escape from ythe last drum of the series into `the smoke-pipe l, outside the-jacket m, which incloses all theI drums. l N i ABy `the seriesof small drums the .smokey-and gases are delayed duri-ng their passage from the maindrum to thej-srnoke-pipe,andthus made to give out more heat than as thoughthey passedstraight away. The greater the number 'of the side drums the greater is `th`e quantity of heat thus saved.V The number of side drumscomhinedlwith any one main drum is varied according to `the amount of heat desired to be producedl i The side drnmsware Open at their lower ends, and

furnished with caps n, which can `be taken on" and put on again withease.

abrd a convenient means of cleaning the latter.

Incase the furnace isinclosed within a brick wall, crooked elbows o are attachedto the bottoms of the side'drnms, instead of the caps n, which elbows pass out through the jacket m and-through the wall, and have caps n on their' outer ends, which can be taken ofi` so as to allow the cleaning of the drums without getting inside the wall.

The elbows o. may be .madeV to 'project from the drums in any direction, 'so as .to accommodate the shape' of the wall.

The feed-collar r, whose inner end opens into the p main drum at the door, and whose outer end opens through the jacket m, is inclined downward, as shown in lig. l. This arrangement not only facilitatesthe tlnowing of fuel into the drum, but'also rendersl it 4easier to get at the ire to rake or adjust it;

We are aware it is-not broadly, new to provide a `stove ordrum with Ia series of smaller drums arranged concentrically therewith to forni an extended flue or passage for the products of combustion, for the purpose of econcmizing fuel,aud we lay no claim to `",such an` arrangement.

Having thus described our invention, That we elairnas new, and desire tosecure by Letters Patent, is-

`The improved furnace herein describetL'cousstiug Vof the' jacket m,.the feed-collar leading into'the main drum and fire-box a, the concentric drums b, c, and d, provided with caps n n, and communicating with the flue l by means of pipe t and the Yconnectingpipes cy h, cachot'` said `parts being constructed. and

arranged asv herein shown and described. i

To the above specification of'our improvement we have set our hands this lith dayof December, 1869.

The caps catch the soot which naturally falls to the bottoms of the chambers. and`
